Thanks... but...
Thanks for the response. I really appreciate that someone has gotten back to me about something that seems like a question that many people would be asking. I should add that I have contacted Apple, which told me that there are ways to restore the deleted files - they just wont tell me how and refer me to unidentified '3rd parties', which is how I wound up here. They also told me that there are ways to view the system log files which will indicate when the Safari browser history was deleted, but, again, wont tell me how!!!
